In present work effect of praseodymium doping on conductivity in a basic plane of HTSC Y1-zPrzBa2Cu3O7-d single crystals are investigated. It is established, that exess conductivity Ds(T) of Y1-zPrzBa2Cu3O7-d single crystals nearby Tc satisfactory described by Aslamazov-Larkin theoretical model. Absolute values of cross-section coherent length xc(0) grow in process of an increase of a praseodymium content. At the same time for samples with z=0.48 sharp enough decrease in size xc(0) that is maybe connected with the general suppression of superconducting characteristics at an come close of praseodymium concentration to z=0.5.
